In this paper, we investigate the performance of a symmetric two-user interference channel with a full-duplex relay (IFRC) from the perspective of diversity-multiplexing tradeoff (DMT). The sources and destinations are all assumed to be equipped with single antenna and the relay is equipped with multiple antennas. We first find a DMT upper bound of the channel by using a channel capacity upper bound...
Plasma excitations in high-electron mobility transistors (HEMTs) with two-dimensional (2D) electron channels can be used for detection, mixing, and generation of terahertz (THz) radiation. Plasmon modes excited in the HEMT channel under the gate contact (gated plasmons) were considered to be more attractive for electronic applications because their frequencies can be effectively tuned by varying the...
